Application iled February 8, 1912. Serial No. 676,417.

To all whom it may concern Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States, and resident of New York, in the county of New York and rState of New York, have invented certain new and useful Improvements in Flexible Roofing, of which the following is a` specification.

This invention relates to roof coverings, which are made of strips of flexible sheet material cut in such manner as to simulate shingles. The roofng`strip used in carrying out this invention is similar to that shown in U. S. Letters Patent No. 908,125, granted to me Dec. 29, 1908.

The improvement to which the present invention relates lies in the manner of laying and securing the roong strips rather than in the structure of the strips themselves. The sheet material of which such strips are made,is thinner than the exposed portions of wooden shingles, and because of the difference inthickness, the roofing does not carry out the simulation of shingles to the desired degree. i

The improvement in securing the lower ends of the tabs according to the present invention, consists in driving a fastener through bothlayers or thicknesses of each of the doubled portions, so that the outer layer will be engaged and held directly by the head of the fastener.

. Of theaccompanying drawings which illustrate this invention, Figure 1 represents an elevation of a blank of sheet material of which the roofing strips are made. Fig. 2

represents anl elevation of a short length of a roofing strip made from the blank show-n in Fig. 1. Fig. 3 represents an elevation similar to Fig. 2, showingthe lower edges of the tabs turned under to give double thickness at the lower ends of the tabs. Fig.

4 represents an elevation showing the pre`- ferred arrangement of succeeding courses of roofing strips. Fig. 5' represents 'a' section in a planeindicated by a line 5-5 of Fig. 4, showing one method of securing `the roong toa foundation. Y D

Similar reference characters indicate the same parts wherever they occur.

A blank-v, of suitable sheet material` forl roofing `purposes is indicated in Fig. 1 at 10.`

This blank is to all` intents and purposes similar to theV one shown in the above-mentioned Patent N.--908,125, withy the exceptransversely and which are disposed so that v each extends an equal distance in both directions from the line 11 of division. Both ends of each slot are closed, thus leaving continuous ymarginal portions 13. The blank, may, if desired, be scored on lines represented by dotted lines 14, 14, whicI are parallel to the line of division and disposed on opposite sides thereof. Lines 14, 14 represent the lines on which the tabs are creased or folded as hereinafter explained.

When the blank is divided on line 11, two roofing strips of identical conguration are provided. One of such roofing strips is indicated in Fig. 2 by reference character 15. The line of division, intersecting the slots 12, provides shingle-like tabs 16. If the blank has been previously scored, as indicated -at 14, each tab will be scored, so that Y its lower edge may be readily folded under as shown by Fig. 3, the portion so folded ance 'with the usual manner ofshingling.- A` io roong foundation is indicated kat 18 in Fig. 5. As each roofing vstrip is laidl upon'the foundation, it is secured thereto byv nails 19, whichv are driven through the upper marginalportion of each strip. When thel entire foundation has been covered by roofing strips attached by nails 19, the individual tabs v16 are secured ashereafter explained,'so as to prevent a wind from lift- .fin'g them. All of the nails 19 which are', used to secure Vone strip, are covered and" protected by the strip next above, so that they are all concealed and so that moisture cannot work along them to the foundation 18.

The means shown by Fig. 5 for fastening down the lower ends of the tabs 16, comprises fasteners 20, whose inner ends are bifurcated and clenched. Each fastener 20 has a head at its outer end and is driven from the exterior and caused to pass through both layers of the doubled portion of a tab 16, and through the "u'pper marginal portion of the roofing strip next below. The nner end of the fastener is clenched against the under side of the strip next below and .is separated from the foundation 18 by the second strip below. Wherever moisture seeps through the layers which are penetrated by the fastener, it will be carried 0E by the layer next the foundation so that it will not reach thel foundation. When all the tabs aare secured in this manner, the

Vwhole number of roofing strips, becomes a `been driven and clenched, and is placed in similar relation to each tab upon the roof,

all of the fasteners 23 being driven and clenched individually.

I claim:

The combination with a supporting surface, of a series of strips of iexible nonmetallic material arranged horizontally thereon, so that each strip overlaps two adjacent lower strips, the exposed edge of each sheet ohaving a series of tabs resembling shingles, the kfree ends of said tabs being folded under to form thickened edges, fasteners securing the upper overlapped edge of each strip directly to the supporting structure, and fastenerssecuring the lower edge of each tab only to the body of the strip directly overlapped thereby, and located over the upper portion .of the lowermost strip. v

In testimony whereof I have athxed my signature in presence oftwo witnesses.
